IMPROVEMENT IN BLIND AND sIuTTI-:R sUPPoRTERs.

'Specification forming partof Letters Patent No. 35,3117, dated May 20,1862.

` Fig. 2, a vertical section of the saine, taken inv the line'x 12,Fig.l Fig'. 3, a detached view of the supporter and fastening; Fig. fhahorizontal section of the saine, taken on the line fg/ y, Fig. Si.

Similar letters of reference indicate corresliiondingl parts in theseveral figures.

To enable those skilled in the art to fully understand and construct myinvention, I

will proceed todeseribe it.

A represents a window-blind, which may be oonstruci'IIaId in the usualway. Thisblind is attached to the window-frame l5 by hinges C C, whichare formed of I eyes a. a, attached to the blind, and pintles l) l,which" are se-V cured to the window-frame, the eyes beingallowedto riseand fall on the pintles l l), as well as turn freely thereon. u Y

In the lower crossfpiece, c, of the blind A there is iitted vertically acatch, I), formed of a pin, d, havingl a square loop or eye, e, at itslower end. lithin this loop or eye e there is placed a spiral spring,j', the upper end of which bears against the upper edge of the loop oreye e, `the lower end bearing` against a Inetal plate, g, which issecnredto the bottoni of the cross-piece c. This spring f `hasa tendencyto keep the pin (Z and its loop or eye e in an elevated state, as willbe fully understood by referring to Figs. 2 and 3, the

scribed.

pin d, it will be understood, being` allowed to rise and fall freely inthe cross-piece o.

E represents a hook, which is secured to the sill 7L of thewilnlow-franie b at its center. Th hook has its upper surface beveled orinclined, as shown at 1', the hook j beingl formed by a recess in itsunder surface, as shown clearly in lfhg'. 2.l The hook E has ahorizontal position, and may be secured to the sill h by having` avertical spike, 7s, at its l innerei'ld, which spike is driven into thesill, the spike and hook bein g in onepiece. .(See Fig. 2. y

F is a hook, which is driven into the building and is :formed preciselylike the hook E, with the exception that its spike end is in line withthe hook end, the spike portion being' driven horizontally into thebuilding'.

From the above description it will be seen that when the blind is closedthe loop or eye e of the pin l is forced overvor on the hook E, and inconsequence of the inclined upper surface, I', of said hook the blindwill beraised or elevated a little so as to take the weight of the blindoli from the pintles I) ZI of thehinges when the loop or eye enters therecess g. The saine result, ii, will be also seen, is attained whenthoblind is peI'Ied. '2y this arrangement, therefore, the blind isprevented from sagging, it is supported at the center of its lower end.

Having thus described 1n y invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination of the catch D with the blind and 'the lifting-hooks EF, in the inanner and for the purpose herein shown and de- 'IHOS- C.BALL. l\"itnesses:
